Wing Installation - Thrush Aircraft S2RHG-T65 TURBO THRUSH Maintenance Manual

THRUSH AIRCRAFT, INC – MODEL S2RHG-T65 TURBO THRUSH
Under no circumstances should the bolts be turned while the
threads are in the spar cap. This could damage the hole
surface finish which could result in a stress concentration.
N. Remove all of the nuts and tube nuts from the upper NAS bolts. Place the
aluminum block on the threaded end of the smallest bolt and with the 4X rivet gun,
drive it flush with the upper splice fitting. Proceed in a similar manner with the
remainder of the bolts working from the smallest to the largest.
O. Using a suitable phenolic or soft metal drift, drift out the NAS bolts from the upper
splice fittings and upper spar cap with a 2X rivet gun working from smallest size
bolt to largest size.
P. Pry the lower half splice fitting off the NAS bolts by tapping phenolic, hard plastic
or aluminum wedges between the lower splice fitting and the upper spar cap.
Remove the lower half of the upper splice fitting. In a similar manner, remover the
upper half of the upper splice fitting.
Q. Remove the bolts securing the center wing splice plate to the right wing. The
splice plate will remain attached to the left wing.
R. Slide the wings directly away from the fuselage lifting the wing roots sufficiently to
clear the fuselage lower longerons.
S. Discard all used nuts, bolts and washers.
To install the wings, proceed as follows using all new nuts, tube nuts, bolts and washers:
All bolt shanks and bolt holes are to be coated with Snap-
On™ General Purpose Antiseize lubricant or equivalent
before installation.
A. If the landing gear is not installed, support the fuselage at a convenient height
using jacks at the landing gear attach points, left and right, and at the aft jack point.
B. On the left wing, install the outboard wing attach angle on the main spar web with
NAS1104-16 bolts, ¼ inch AN960 and MS20002C washers and MS21042 nuts.
Torque the MS21042 nuts per Table 7-1, six places.
